How to force VSCode to use locally installed TypeScript

Question

Is there a way to force Visual Studio Code to use the TypeScript installed locally in a JS project (instead of the version bundled with VSCode, or the version installed globally) for type checking when editing that project?

Answer 1

I assume that you have installed TypeScript in the myProject directory.

cd myProject
npm install --save-dev typescript

If you have already done that, then add a .vscode/ directory with a settings.json file that specifies the TypeScript SDK to use:

{
    "typescript.tsdk": "node_modules\\typescript\\lib"
}

This is the final directory structure:

myProject
  .vscode
    settings.json
  node_modules
    typescript
      lib

Important: make sure that you open VSCode in the myProject directory!

The VS Code documentation calls this "using the workspace version of TypeScript."
